We didn't have that in the eight-millimeter days. We had to lug a projector, we had to plug it in to somebody's wall, put up a screen and show it to someone patient enough to sit there for five minutes and watch.

So now, I'm gonna plug in 8 here and now finally, 24 that's 16 so that's plus 8, so that's 24.
这儿用8代入,就是16加8,等于。
And in terms of equations that we use, it's sometimes easier to plug in the fact, since momentum is equal to mass times velocity.
在我们使用方程这方面,事实上有时是很容易代入的,因为动量等于质量乘以速度。
